The study, led by Professors Sang Ouk Kim and Hyun Jung Chung, shows graphene oxide targets the bacterial membrane molecule POPG, leaving human cells unharmed.
This mechanism enables graphene oxide nanofibers to halt growth of antibiotic-resistant bacteria, accelerate wound healing in animals, and retain antibacterial power after repeated washing.
Commercial products like a graphene antibacterial toothbrush have sold over 10 million units, and the technology is being used in textiles for sportswear, with potential applications in wearable devices and medical fabrics.
Can superbugs evolve to outsmart even graphene's precise bacterial-killing mechanism?
Will our fight against superbugs with graphene create a new environmental crisis?
Beyond toothbrushes, when will these smart graphene textiles become part of our daily wardrobe?
Is graphene oxide's 'safe' label hiding long-term health risks not yet discovered?
Could this bacteria-killing technology be reprogrammed to seek and destroy cancer cells?
With multiple graphene weapons emerging, which will win the global war on germs?
